Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for completeness and fully convey the scope of the invention to the skilled person.
Example one

In this embodiment, the oxygen generator produces 93% oxygen by electrolyzing water and introduces the oxygen into the mixing chamber 2, the natural gas generator is a natural gas pipeline, natural gas is introduced into the mixing chamber 2 through the natural gas pipeline and mixed with the 93% oxygen, and then the mixed gas is sprayed into the melting furnace through the third gas passage 9 for combustion.
In the present embodiment, the three spools 6 control the intake states of the three air passages, respectively.
In this embodiment, the natural gas mainly contains alkanes, wherein methane is the majority, and a small amount of ethane, propane and butane, and further generally contains hydrogen sulfide, carbon dioxide, nitrogen and water vapor, a small amount of carbon monoxide and a small amount of rare gases, such as helium and argon, etc., and oxygen is prepared by using an oxygen generator, wherein the prepared oxygen concentration is 93% instead of using an oxygen cylinder, and the oxygen prepared by using electrolytic water in the actual use process has the using effect of the oxygen cylinder which can reach 97% concentration, so that the cost of recovering waste copper in the copper rod production process is reduced, but the oxygen prepared by using electrolytic water in the oxygen generator contains a large amount of water vapor, and water drops are condensed on the inner wall of the valve body 1 when oxygen with a large amount of water vapor passes through the mixing valve at a high speed (in a period of time when the mixing valve is just started to work, the temperature of the mixing valve is not raised yet, so that a temperature environment for forming water drops is provided), the natural gas contains a small amount of hydrogen sulfide, the hydrogen sulfide is contacted with high-concentration oxygen in the valve body 1, mixed and oxidized into sulfur dioxide, the sulfur dioxide is dissolved in water drops on the inner wall of the valve body 1 to form sulfurous acid liquid, the sulfurous acid liquid is oxidized into dilute sulfuric acid liquid drops by the high-concentration oxygen, so that the dilute sulfuric acid liquid drops are finally condensed on the inner wall, the dilute sulfuric acid liquid drops on the inner wall of the valve body 1 are difficult to clean, after a period of time, the valve body 1 can bear higher combustion temperature (no temperature environment for forming water drops is provided at this time), the boiling point of water in the formed dilute sulfuric acid liquid drops is lower than that of sulfuric acid, so that water is volatilized first, concentrated sulfuric acid liquid drops with the concentration of 98.3% are finally formed, after the mixing valve is repeatedly cycled for many times, more concentrated sulfuric acid liquid drops can be accumulated on the inner wall of the valve body 1, and the valve body 1 is corroded by the concentrated sulfuric acid liquid drops under the condition of high-oxygen concentration for a long time, so that the service life of the mixing valve is less than half of that of normal use.
In order to solve the problem that the valve body 1 is eroded by concentrated sulfuric acid droplets under the condition of high oxygen concentration for a long time, the mixing valve further comprises a blocking block 11, one end of the mixing cavity 2 penetrates out of the valve body 1, the end of the mixing cavity 2 penetrating out of the valve body 1 is an opening end, the blocking block 11 is arranged in the opening end of the mixing cavity 2, and the blocking block 11 is used for closing the opening end of the mixing cavity 2.
After using at every turn, the staff need unscrew the sprue 11, then spill some organic matter powder into mixing chamber 2, for example, flour for organic matter powder and the concentrated sulfuric acid liquid drop of remaining and gluing on mixing chamber 2 inner wall take place the carbonization reaction, make the concentrated sulfuric acid liquid drop consumed, the powdered carbon that generates can be easily scraped off, in time clear away the concentrated sulfuric acid liquid drop on mixing chamber 2 inner wall, thereby prevent that valve body 1 from being corroded by the concentrated sulfuric acid liquid drop under the high oxygen concentration condition for a long time, improve the life of mixing valve with this.
Further, the block 11 is screwed in the opening end of the mixing chamber 2, so that the block 11 is convenient to disassemble and assemble.
Example two
In the first embodiment, although concentrated sulfuric acid droplets on the inner wall of the mixing chamber 2 can be removed in time by cleaning each time, each cleaning must be performed after the mixing valve is used once, and during the use of the mixing valve, concentrated sulfuric acid droplets are formed on the inner wall of the mixing valve to erode the mixing valve, so that the first embodiment can only solve the erosion problem of part of the concentrated sulfuric acid droplets on the mixing valve, and meanwhile, each time the block 11 is opened to clean, the operation is cumbersome, the matching precision of the block 11 and the opening end of the mixing chamber 2 is reduced, and high-pressure gas in the mixing chamber 2 is easy to leak, for this reason, the present application proposes another solution, as shown in fig. 2-5, the difference from the first embodiment is that the mixing valve further comprises organic particles 12 and a filter block 13, the mixing chamber 2 is a concave cavity with a crescent shape in a cross section, left part interface channel 3 and right part interface channel 3 are located 2 upper portion both sides of hybrid chamber respectively, and middle part interface channel 3 is located the centre on 2 upper portions of hybrid chamber, and organic granule 12 distributes in hybrid chamber 2, all is provided with filter block 13 on the bottom in the three slide 4, and disk seat 5 all is located filter block 13, and the diameter of the filtration pore in filter block 13 is less than the diameter of organic granule 12.
